Normally I'm the same way but I actually use 2 of the 4 rigs running right now so raw performance is important to me for other reasons. What I mean is, since the BD rig will replace one of my 1090t's, my main interest will be how it performs on normal cpu intensive tasks like transcoding, encrypting, archiving, etc. If it does well overall it will probably be a good cruncher.

BD though is going to be a different animal though since each module only has one fp unit. So you'll have 8 cores but only 4 fpu's. Of course that's also true for Intel's hyperthreaded i7's so maybe that won't mean much, but we'll have to see.
